Patent number: 7959547Abstract: The invention relates to a centrifuge for the cleaning of a liquid, in particular a lubricant oil of an internal combustion engine. Said centrifuge comprises a housing, at least one bearing element on the housing side and a rotor which is rotatably mounted thereon. The rotor is composed of at least two parts, an inner part for accommodating the bearing and a part for retaining impurities in an impurity collection zone, wherein said part may be detached from the inner part for maintenance of the centrifuge. The centrifuge is characterized in that the/each bearing element is an element composed of a first bearing material and comprises one or more first smooth bearing surfaces. The inner part, embodied as a single piece, is made of a second bearing material and provided with one or more second smooth bearing surfaces. First and second bearing surfaces cooperate directly among each other, and the first and second bearing materials form a pair of smooth bearing materials.Type: GrantFiled: November 17, 2006Date of Patent: June 14, 2011Assignee: Hengst GmbH & Co., KGInventors: Dieter Baumann, Uwe Meinig

Publication number: 20090199826Abstract: A device for eliminating oil particles from the crankcase ventilation gas of an internal combustion engine. The device is located in the flow duct of the gas that runs from the crankcase to an induction tract of the engine. The device includes an oil separator in the form of an outlet for the gas with a deflection of the flow, causing the oil particles to be deposited on a baffle surface and thus to be eliminated from the crankcase ventilation gas flow. The device has an infeed cross-section, which lies upstream of the baffle surface when viewed from the flow direction of the crankcase ventilation gas, and which is sub-divided into several infeed sub-sections. The baffle surface is a solid surface that is devoid of perforations. The baffle surface is configured on a valve body, which lies downstream of the infeed sub-sections when viewed in the flow direction of the gas, and which is pre-tensioned by a force.Type: ApplicationFiled: June 24, 2006Publication date: August 13, 2009Applicant: HENGST GMBH & CO.

Patent number: 6591856Abstract: A safety valve, such as for a refueling vent line between the tank filler neck and the active charcoal container in a motor vehicle. The safety valve is inserted into the refueling vent line being configured as a float valve. When fuel penetrates into the refueling vent line, and thereby into the safety valve, the outlet of the safety valve is closed by the float. The safety valve is provided with an anti-pollution pipe-end opening onto the environment and closed at normal pressure by a closure operated by a diaphragm. At an elevated pressure in the safety valve, the diaphragm effects an opening of the closure at the anti-pollution pipe-end.Type: GrantFiled: October 31, 2001Date of Patent: July 15, 2003Assignee: Firma Carl FreudenbergInventors: Uwe Meinig, Jörg Bittner

Patent number: 5480016Abstract: An input component (3) of a clutch is fastened to the output end (5) of the crankshaft (7) of an internal combustion engine by a force-fit coupling (11) in which a radial force fit is produced by axial forces which are applied to the coupling (11) by a tool inserted through the hub (21) of a clutch disc (23) or applied to the hub, which in turn applies the axial force on the coupling. The coupling enables the clutch (1), including the flywheel (3) and the clutch disc (23), to be installed on the crankshaft (7) as an assembled unit. The force-fit coupling (11) comprises an expanding conical, element (61), arranged in a central opening (59) of the output end (5) of the crankshaft (7), which expands the output end (5) of the crankshaft radially.Type: GrantFiled: March 21, 1994Date of Patent: January 2, 1996Assignee: Fichtel & Sachs AGInventors: Walter Kurz, Wolfgang Baier, Uwe Meinig
